  • Publication number: 20180196742
    Abstract: Software testing techniques based on image recognition are disclosed. In various embodiments, a programmatically implemented image classifier is trained to recognize a screen shot image as being associated with a transaction end condition of a transaction. A test script configured to initiate an iteration of the transaction is run. A start time of the iteration of the transaction is recorded. Screen shot images are generated during performance of the iteration of the transaction to capture a series of screen shot images of at least a portion of a user interface display associated with the iteration of the transaction. The image classifier is used to find an earliest-captured image that matches the transaction end condition. A time associated with the matched image is used as a transaction end time to compute an end-to-end time to perform the iteration of the transaction.

  • Patent number: 9721040
    Abstract: A mechanism and accompanying method adapted for use with a user interface for manipulating complex data strings. In an example embodiment, the method includes providing a dialog box that includes a first user option to input data pertaining to a complex data string; using data input pertaining to the complex data string to selectively verify that portions of the complex data string represent valid portions; providing a first user option via the dialog box to employ data input pertaining to the complex data string as one or more search criteria to selectively perform a search of preexisting complex data strings; and providing search results in response thereto, wherein the search results are displayed within the dialog box. In a specific embodiment, the method further includes providing a mechanism via the dialog box to trigger creation of a complex data string that a user has specified via the dialog box when search results for the complex data string to be created do not include a match.

  • Patent number: 9026701
    Abstract: A method, system, application programming interface, and computer program product that enable enterprise data management application programs to request input/output services from a device manager controlling devices. The device manager operates in a heterogeneous environment including incompatible devices provided by multiple vendors. These requests, and responses from the device manager to the enterprise data management application program, are communicated in a markup language format, rather than in a device-specific native language. This structure enables the vendor of the enterprise data management application program to send requests for services, including both data and instructions to use specialized features of a device, without the need to change the enterprise data management application program to support device-specific native languages.
